I need help with #29 I really don't understand it (picture included)

Katena32 [7]

4x+4(3)+4(2)=y
4x+20=y
X equals the amount it cost for each ticket which is unknown. Y equals the total cost. Because the amount of the food is provided, it can be calculated unlike the tickets which is just left at 4x. The work for the snacks are upwards. Its mostly substitution.

Schach [20]

Answer:

1. 30 student

2. 120 student's didn't vote

3. 7 quarters

Step-by-step explanation:

1. first, see how many games can be played:

45÷3 = 15

then, multiply the number of games by two because 2 students can play per game

15 • 2 = 30

2. first, figure out what percent of students did not vote:

100 - 60 = 40%

then, multiply the number of students total (300) by the decimal of the percent that did not vote to find the number of students who didn't vote:

300 • .40 = 120 student's didn't vote

3. first, find how much 9 dimes is:

1 dime = $0.10

9 dimes = 9 • $0.10 = $0.90

then, find how much money kerry had:

$2.65 - $0.90 = $1.75

finally, find out how many quarters kerry had by dividing the amount of money she had by the worth of a quarter:

1 quarter = $0.25

$1.75 ÷ $0.25 = 7 quarters

Hi, umm pls help 1/6(x-5)=1/2(x+6), solve for x And can you please explain

Mumz [18]

Answer:

By solving the equation $\frac{1}{6}(x-5)=\frac{1}{2}(x+6)$ we found that $x=\frac{23}{2} \text { or }=11 \frac{1}{2}$

Explanation:

Given equation,

$\frac{1}{6}(x-5)=\frac{1}{2}(x+6)$ to find x

Step: 1 Cross multiply the denominators 2(x-5)=6(x+6)

Step: 2 Open brackets and simplify the term 2x-10=6x+36

Step: 3 Bring x terms on one side and simplify the equation the equation obtained is following,

2x-6x=36+10

-4x=46

$-x=\frac{46}{4}=\frac{23}{2}=11 \frac{1}{2}$

Therefore, we solved x value from the given equation $\frac{1}{6}(x-5)=\frac{1}{2}(x+6)$ as $x=\frac{23}{2} \text { or }=11 \frac{1}{2}$ .
